U+2A20 "⨠" Z Notation Schema Piping Unicode Character

U+2A20 "⨠" Z Notation Schema Piping is a mathematical symbol used within the Z notation formal specification language, where it serves as a binary operator to combine two schemas by merging their declarations and conjoining their predicates, with the right-hand schema's inputs being matched to the left-hand schema's outputs. This piping mechanism facilitates the sequential composition of operations, allowing the output of one schema to feed directly into the input of another, much like a pipe in a shell command. The symbol resembles a rightward double arrow with a vertical stroke, distinguishing it from simpler arrows or turnstile operators, and it is encoded in Unicode’s Supplemental Mathematical Operators block to support precise documentation and software tools for formal methods.
